'Application filed May 16. 1907. Serial No. 373.999-

To all whom'it may concern:

Be it known that l, ALLEN I. MERCER, citizen Aof the United States,residing at Manningtomuin the county of Marion and State of ,WestVirginia, have invented certain new and' useful Improvements in Music-Leaf Turners, of which the following is a speciication'.

This invention has for its object a simple, durable and-etlicientconstructionl of music leaf turner by which the pages of a music book orother musical composition may be quickly turned in succession at theproper l.time 'and vuithprecision, and the :lI

invention consists in certain constructions, arrange- Alnie'nts'andcombinations of the parts that` I 1 'shall hereinafter fully describeand claim. For a full understanding of the invention and the meritsthereof and also tovacquire a 'knowledge of the details of constructionand 'the means for effecting the result, reference is to be had to thefollowing description and 'accompanying drawings, in which:

cured to any desired stand or to musical instruinents by any suitableclamps, so that the device may be easily attached or removed.' Withinthe case 1 a toothed segment 2 is mounted, said segment being actuatedin one direction by means of a spring 3 v and being provided with ahandle l which projects forwardly out of the open side'of the case,wi-thin convenient reach of the opera tor. A stop pin el is mountedwithin the case and is adapted to abut'against the handle when thesegment is turned 'in one direction, and against the body portion ol thesegment when the latter is 'turned in the opposite direction, so as tolimit the movements of said segment. The segment 2 meshes with a pinion5 secured fast" on a. vertically extending shaft 6 journaled at itslower end in the case .1. A plurality of telescoping tubeS'are mountedto turn and slide loosely on the said shaft 6, three of said tubes beingshown in the present instance, designated 7, S and 9,'although it is tobe understood that my invention is 'not limited to any number. Theoutermost tube -9 is provided with a opensl downwardly at the lower endof the tube, and the next inner tube S is similarly provided at itslower edge with a. bayonet rlhe shaft 6 is provided. near its "l'owerendwith a radially extending pin 12 adapted to describe the arc of acircle, as the shaft is rotated, and coming to rest at one limit ofmovementof the shaft over a shoulder 12 which is in the form of a. ledgeor proximity tQ/thefbaseftlse shaft on the top plate oftheycase 1. Theoutermost tube 9 rests upon said shoulder in elevated position, when theparts are in readiness for operation. Each of the said tubes 7, 8 and 9is provided with an 'outwardly projectingstudjl, and arms 14 arepivotally connected at one end to the respective studs of the tubes,said arms being preferably extensible, as clearly illustrated tween thestud and the arm is. arranged so 'that the arm may be dropped downagainst the tube so as to occupy a minimum amount of space whenthedeviceis not beingused. Each of the arms 1st carries a clip 15 of anydesired type or formation, the said clips being adapted to be secured tothe edges of the respective leaves of the book or musical comarms areswung around in a manner' now to be set forth.

ln the practical 4operation of my improved music leaf turner, it is tobe understood that an elevated position upon the shoulder 12a 'and' thatthe inner tubes 7 and 8 rest insuccessive and at still higher elevationswith their studs supporting them by extending over the next outermosttube. Hence the bayonet slot of the inner tube or tubes will be heldabove or out of alinenient with the bayonet slot of thenext outer tube.As the segment 2 is then actuated by the operator, the pin 12 willenterv the bayonet slot of the outermost tube and by engaging the tubewill revolve the same until the said verticalportion of the slot comesinto registry with the shoulder 12a, whereupon the said tube bayonetslot 10, the vertical portion of .whichj in the drawing. -The `jointbe!A position, so as to turn the leaves when the will drop/down vuponthe opposite sides of .at the outset the outermost tube 9 rests in 'saidshoulder.

This will manifestly effec-t the turning over of one leaf.

i bayonet slot, but in lieu thereof it must be provided with aprojection or shoulder such as indicated at 16, so that it may beengaged by the tube.

F rom the foregoing description in connection with the accompanyingdrawings, it will be seen that l have provided a very simple'.

and efficient constructionV of music leaf turner in which thetelescoping tubes are so arranged as to be expeditiously operated andwith precision at every actuation of the toothed segment 2. In order to'set the device, the .pin 1Q will be held over and in alinement with theshoulder l2, so that the tubes may be raised and turned back and theirseveral arms engaged with the leavesv of the book or sheet of music.

Having thus described the invent-ion, what is vclaimed as new is:

l. A music leaf turner, ctnnprising a support, a vertical shaftjournaled on said suport means for. turning said shaft. said shaft beingprovided with a pin, and the support being provided with anupwardlyextending shoulder with vwhich said pin is adapted to registerupon the rotation of the shaft, a plurality of teleseoping tubes looselymountedon said shaft, said tubes being provided in their lower edgeswith bayonet slots with which said pin isladapted to successively engageso as to turn the tubes in succession, the tubes being adapted to dropone after the other over the shoulder, and arms carried by therespective tubes, said arms being each provided with means for attachingit to a leaf.

2, A. music leaf turner, comprising a support, a vertically extendingshaft iournaled on said support and provided with a radially extendingpin, means for turning said shaft back and forth on the support, thesupport being provided with` a shoulder with which said pin is adaptedto register upon the actuation of the shaft, a plurality of teleseopingtubes loosely mounted to move vertically and revolve on said shaft, said'tubes being provided in the lower edges with downwardly openingbayonetv slots adapted to successively pass down over the shoulder andalso adapted to be successively engaged by the pin so as to carry themaround towards the rlhe handle of .y the toothed segment will then bereleased.v

ascesa shoulder, said tubes being provided at their upper face withstuds, and the stud of one tube extending over the upper edge of thenext outermost tube and adapted to hold its' tube at a higher elevationthan the said next outermost tube, whereby the bayonet slots of' theseveral tubes will be normally out of aliuement, and arms carried by therespective tubes, said arms being provided with n'ieans for attachingthem to the leaves.

3. A music leaf turner, comprising a support, a vertical shaft journaledon said support, means for ,turning said shaft, said shaft being`provided with a pin, and the support being provided with an upwardlyextending shoulder with which said pin is adapted to registerupon therotation of the shaft, a plurality of telescoping tubes loosely mountedon said shaft, said tubes being provided in their lower edges withbayonet slots with which said pin is adapted to successively engage soas to turn they tube in succession, the tubes being adapted to drop one4after the other over the shoulder, and arms carried by the respectivetubes, said arms being each provided with means for attaching it to aleaf, said arms having a joint-ed connection. with the tubes, wherebythey may be folded againstV the same.

4. A music lea-f turner, comprising a supporting case, a toothed segmentmounted in said case and spring pressed in one direction, a pinion withwhich said segment meshes, a vertically extending shaft journaled insaid case and vto which said pinion is secured, said shaft beingprovided with a radially extending pin near its lower end, the casebeing provided with an upwardly extending shoulder with which said pinis adapted to register, a

sion may drop over the shoulder, and arms carried by the respectivetubes,y said arms being provided with means for attaching them to theseveral leaves of a music book or the like.

In testimony whereof l affix my signature in presence of two witnesses.

ALLEN I. MERCER.
